The Diachrony of Subjunctive-Infinitive Competition in Balkan Slavic Typological vs. Sprachbund Phenomena

The paper analyses the phenomenon of infinitive loss in Balkan Slavic in the context of the broader cross-linguistic process of subjunctive-infinitive competition (SIC). I adopt a diachronic perspective, analysing the historical developments pertaining to SIC in languages ranging from Old Church Slavonic to present-day Bulgarian and Serbian. The main goal of the paper is to distinguish between those instances of Balkan-Slavic infinitive loss that are a result of broader typological processes and those that can be viewed as genuine Balkan-sprachbund innovations. The specific Balkan innovation in this context was the replacement of infinitives by finite subjunctives in obligatory subject-control environments. I analyse this diachronic development as the result of a formal reanalysis affecting the syntactic status of the Balkan-Slavic subjunctive marker, which allowed it to spread to obligatory-control structures.
